我最近在读cBLAS的一些源代码,有些事情让我不清楚。在许多函数中,.c 文件调用 Fortran Wrapper,而不是直接在 C 文件中编写代码,如下文件:
/*
* cblas_sdsdot.c
*
* The program is a C interface to sdsdot.
* It calls the fortran wrapper before calling sdsdot.
*
* Written by Keita Teranishi. 2/11/1998

#include "cblas.h"
#include "cblas_f77.h"
float cblas_sdsdot( const int N, const float alpha, const float *X,
const int incX, const float *Y, const int incY)
{
float dot;
#ifdef F77_INT
F77_INT F77_N=N, F77_incX=incX, F77_incY=incY;
#else
#define F77_N N
#define F77_incX incX
#define F77_incY incY …Run Code Online (Sandbox Code Playgroud)
